To put this idea to the test, the researchers asked a group of young nurses to watch a disturbing video then tell an interviewer that they had actually seen a pleasant one. Additionally, a young humans feedback conditioned response is largely conditioned by their satisfaction with the observers response and this is colored by the validity of everyones interpretations of the others behaviour. Your head and body might move back a bit, as well. One third of the people enrolled in the experiment complied, beheading the rat as best they could. Another function of smiling (and one that anecdotal evidence supports) is that it enhances our attractiveness.

In a more recent study, published this year in Psychological Science, Ernest Abel and Michael Kruger of Wayne State University extended this line of research from emotional outcomes to a biological one: longevity. While animal experimentation can be incredibly helpful in understanding man, and developing life saving drugs, there have been experiments which go well beyond the realms of ethics. Wendell Johnson conducted a speech experiment on 22 orphaned children with normal language development. For instance, is there one expression everyone uses to convey shock, and another commonly used to display disgust. Our basic research question is to what extent facial and vocal emotion recognition software can be used for improving communication skills training.

Landis facial expression Experiment Carney Landis conducted an experiment in 1924, where he took willing participants and drew black lines on their face to mark where all their muscles were, to help show muscle movement in the persons face face reacting.

The purpose of the experiment was to find out the degree of obedience to an authority figure, which required inflicting suffering on another person. As each person reacted, they were photographed by Landis. In 1924, Carney Landis, a Minnesota University graduate student, set out to understand experimentally whether these physiological changes are the same for everybody. He didn't believe that average people could intentionally make the same faces that they naturally made when really reacting to emotions (this turned out to be his most accurate prediction), and so he took steps to simulate people reacting to things that would bring them joy, laughter, curiosity, contentment, physical pleasure, and happy anticipation. The consequences of the study were actually more important for their evidence that people are willing to do almost anything when asked in a situation like this.
